VOOHU WHSG24301GM can replace Pulse Electronics HX5120NL. See the evaluation reports below for details.

| Pulse Electronics | HX5120NL | Replacement | HX5120NL evaluation report |
Based on VOOHU replacement evaluations. Check both datasheets and validate with samples before switching.
Yes – the WHSG24301GM has a +125 °C upper operating limit, a step above the common +85 °C class.That is the component's own temperature boundary rather than an allowable ambient, so cabinet temperature plus the part's self-heating both have to land within it. Measure the component temperature at the highest planned internal temperature and worst airflow.
The part does not support PoE, so the port has to be powered locally. Other options are listed in the10/100/1000 BASE-T range.
No – the measurement conditions differ, so the two numbers are not directly comparable.The WHSG24301GM OCL is measured at 100 kHz and 0.1 V, while PoE parts in the same family add a DC bias: theWHSG24701D1states the same 350 μH but with 8 mA of bias.
Bias shifts the core's operating point, so an OCL value quoted without its bias condition carries no comparative meaning. For incoming inspection or supplier comparison, set the fixture to the condition documented for that specific part.
Decide on the low-temperature end: below -40 °C take theWHSG24301JM, and if -40 °C is enough take the WHSG24301GM.The two share an identical package, recommended pad layout, pin-to-net mapping and high-frequency limits, and both reach +125 °C at the top.
They differ at the cold end and in the OCL entry: the WHSG24301GM documents an OCL figure while the current WHSG24301JM datasheet does not list one, so choose the WHSG24301GM where incoming inspection has to judge against OCL. Because the mechanicals are identical, switching between them needs no board change.
